Abstract: Aspects directed towards sounding reference signal (SRS) antenna switching are disclosed. In one example, an SRS configuration is received from a network in which at least four antennas of a scheduled entity are configured based on the SRS configuration. Here, the SRS configuration configures at least one antenna to simultaneously support SRS antenna switching and an uplink (UL) multiple-input multiple-output (MIMO) communication. An SRS communication is then transmitted according to the SRS configuration. In another example, a transmission capability reporting is received from a scheduled entity comprising at least four antennas. A determination is then made of whether the scheduled entity may simultaneously support SRS antenna switching and an UL MIMO communication. An SRS configuration is then generated for the scheduled entity based on the determination in which a default SRS configuration configures at least one antenna to simultaneously support the SRS antenna switching and the UL MIMO communication.

The UE transmits a physical uplink shared channel (PUSCH) to the base station using SRS resources from the selected SRS resource set.

Abstract: The transmission and reception group delay in a front end structure of a mobile device may be determined using closed loop calibration. The closed loop may be a near field radiated closed loop between pairs of antennas in an antenna array of the mobile device. The delay based on time of transmission and time of reception may be measured for a plurality of pairs of antennas, from which the transmit and receive group delay within a single path may be determined. The propagation delay of the signal between antennas may be included in the group delay calibration for increased accuracy. In another implementation, a conducted closed loop, e.g., in the transceiver or in a radio frequency switching network may be used to calibrate the group delay. Pre-characterization of the delay caused by components between the closed loop and antennas may be included in the group delay calibration for increased accuracy.

Abstract: A base station may identify an association between a set of physical cell identifiers (PCIs) identifying different transmission reception points (TRPs) and a set of transmission configuration indicator (TCI) states for a user equipment (UE). The base station may transmit a TCI state and PCI association indication to the UE. The UE may receive a downlink transmission using a receive beam associated with a TCI state, and may identify a PCI of the set of PCIs to use to decode the received downlink transmission. In cases where the TCI state used to receive the downlink transmission is associated with multiple PCIs, the UE may select a default PCI from the multiple PCIs, and may decode the received transmission accordingly. In some examples, the UE may receive reference signals from one or more of the serving TRPs and may identify a PCI to use to decode the received reference signals.
